What's New in the Solaris 10 10/09 Release for Installation

ZFS and Flash Installation Support

Starting with the Solaris 10 10/09 release, you can set up a JumpStart profile to identify a Flash archive
of a ZFS root pool.

A Flash archive can be created on a system that is running
a UFS root file system or a ZFS root file system. A Flash
archive of a ZFS root pool contains the entire pool hierarchy, except for
the swap and dump volumes, and any excluded datasets. The swap and dump
volumes are created when the Flash archive is installed.

You can use the Flash archive installation method as follows:

Generate a Flash archive that can be used to install and boot a system with a ZFS root file system.

Perform a JumpStart installation of a system by using a ZFS Flash archive.

Note - Creating a ZFS Flash archive backs up an entire root pool, not individual boot environments. Individual datasets within the pool can be excluded by using the flarcreate and flar command's -D option.

Two-Terabyte Disk Support for Installing and Booting the Oracle Solaris OS

In previous Oracle Solaris releases, you could not install and boot the
Oracle Solaris OS from a disk that was greater than 1 TB in
size. Starting with the Solaris 10 10/09 release, you can install and boot the Oracle Solaris OS from a
disk that is up to 2 TB in size.

Starting with the Solaris 10 10/09 release, you can use the VTOC label on a disk of any size,
but the addressable space by the VTOC is limited to 2 TB. This
feature allows disks that are larger than 2 TB to be used as
boot drives, but the usable space from the label is limited to 2
TB.

Note - This feature is only available on systems that run a 64-bit kernel. A
minimum of 1 GB of memory is required for x86 based systems.
